Thank you Kevin!
Undercoat in one of the sandy Humbrols, can't remember which 62 or 63. Then in oils W&N Gold Ochre darkened with a spot of Burnt Umber,the first highlights in the fresh with W&N Naples Yellow Dark. When dry more highlights with NYD and extra touch up on pockets etc. in Naples Yellow Light. Usually I finish with highlighting 'wet on dry' and finely 'feathering out' to blend the whole thing, because in the past because of my job I rarely had the time to finish something in one sitting. Now retired I keep to the same method.
Cheers,
Pierre
